Self-heating container

ABSTRACT

The present invention relates to a heating container. There are types of food which should be eaten after being warmed up at home or in a restaurant. Hot sops or hot stews can be eaten after being heated on a portable gas range. However, it is impossible or very inconvenient to heat pan-fried foods, boiled beef, fried foods, rice cakes and the like on a gas range. The heating container of the present invention has a self-heating function and is very useful because the heating container allows food to be kept warm until the end of the meal when various foods are placed on the heated heating container, whereby enabling the distinct tastes of the foods not to be lost until the end of the meal.

TECHNICAL FIELD

The present invention relates to a self-heating container which is different as compared to a conventional heating container which is designed to be directly heated and is currently, widely used. Since the conventional heating container does not have a self-heating function, the increased heat is gradually cooled as time passes. In the event that the heat is increased to a high level in an attempt to keep the increased heat lasting long, the heat becomes too hot at the very beginning of heating, and then the heat is gradually cooled, so there is a big heat difference, which might make foods have no taste, and it is inconvenient to use.

BACKGROUND ART

Most of housewives does a lot of work at home making foods, and the tastes of foods at a restaurant might be a key factor which determines the success of the business, so a lot of efforts is contributed to making the foods have taste. When a certain food which needs to keep warm until the end of meal is fast cooled on a table, a restaurant guest might not enjoy eating the well cooked foods, which leads to ruining a restaurant business. Therefore, it is important to make the foods have taste as well as it is important to facilitate the heat of the foods to last until the end of meal. In terms of the forgoing, a self-heating container according to the present invention can be very useful since it is possible to keep the initial heat of the foods until the end of meal.

DISCLOSURE OF INVENTION

Accordingly, it is an object of the present invention to provide a self-heating container which has a self-heating function, an easier heating control, a function generating a certain level temperate appropriate to a corresponding food, and a function making the temperature last long, with the container being repeatedly used, along with a reliable safety and low cost feature.

To achieve the above objects, there is provided a self-heating container characterized in that a self-heating function is implemented using a solution such as sodium acetate, sodium thiosulfate, etc. or an aqueous solution generally used to manufacture a hand-held stove, and a snap button type impact device capable of impacting a heating trigger member is used to make a module-type operation kit which results in an easier operation, thus engaging the module at the container. When the amount of the material is a lot, a longer heating time is needed depending on the thickness of the container, and when the amount of the same is small, the heating time relatively shortens. The high and low of the temperature can be adjusted by adjusting the amount of a solution such as sodium acetate, sodium thiosulfate, etc. or the amount of an aqueous solution and the ratio of water, and the container used is inputted into boiling water or is processed to have required conditions for the use at the microwave range. All the elements of the self-heating container are cheap, and an efficient self-heating container can be manufactured.

MODES FOR CARRYING OUT THE INVENTION

The preferred embodiments of the present invention will be described with reference to the accompanying drawings. FIG. 1 is a cut-away perspective view of a self-heating container configured in such a way that a double container inner space part 12 is formed of a double container upper layer 10 and a double container lower layer 11, thus defining a typical container shape, and the double container is formed of the double container inner space part 12, and an impact module 35 is engaged at the center of the double container inner space part 12. As shown in FIGS. 2 and 3, the impact module 30 is engaged in the double container inner space part 12 of the self-heating container. The impact module 30 is configured with its outer edges being protruded in a small container shape, and is equipped with the impact module inner space 17. The protrusion parts are formed at its lower and upper sides, thus defining the assembly groove 16, in order for the assembly groove 16 to be formed at the upper sides of the outer circumferential protrusion portions. The impact elastic member means 21 is provided in the assembly groove 16, with its upper side being convex, with its lower side being concave. The impact elastic member means 21 might be formed in a polygonal shape; however in the present invention, a circular impact elastic member means 21 is provided. A recovery spring 20 is engaged at a lower side of the impact elastic member means 21, thus recovering the impact elastic member means 21. The recovery spring 20 according to the present invention is adapted for the use of a use impact elastic member means as a spring means, but might be replaced with another elastic member means having different types of elastic forces. The protrusion part 22 with the double container upper layer 10 is provided in the vicinity of the upper side of the impact elastic member means 21, so when a user artificially pushes the center where the protrusion part 22 of the double container upper layer 10 is disposed, the protrusion part 22 strongly pushes the impact elastic member means 21, and the impact elastic member means 21 is remains with its outer edge being caught by means of the escape prevention shoulder 14, so the convex and concave shapes are inverted, namely, the upper side becomes concave, and the lower side becomes convex. In this state, the impact elastic member means 21 stores elastic forces. When a user releases his hand from a pressing state of the double container upper layer 10, the protrusion part 22 no longer pushes the impact elastic member means 21, and the impact elastic member means 21 can recover for itself; however the impact elastic member means 21 can be more easily recovered since it was previously compressed. At this time, since the recovery is fast performed, the impact is high. Here, since it is caught by means of the escape prevention shoulder 15, it does not escape from the assembly groove 16, and a solution such as sodium acetate, sodium thiosulfate, etc. and an aqueous solution in the double container inner space part 12 is reacted by means of the recovery impact, and reaction heat is generated, thus heating the double container upper layer 10 and the double container lower layer 11, so the entire portions of the container are heated. As shown in FIG. 4, the impact module 32 has a protrusion part 23 at a curved upper side of the center of the impact elastic member means 21, which protrusion part functions as the protrusion part 22, thus reliably forming an impact module 32. The impact module 35 of FIG. 5 is configured in such a way that the slide cover 34 is covered on the upper side of the impact module 30, and the protrusion part 22 is provided in the interior. When the double container upper layer 10 is pressed, the slide cover 34 is pressed, and the protrusion part 22 disposed at an inner center portion of the slide cover 34 serves to press the impact elastic member means 21. FIG. 6 is a view illustrating a construction that the slide cover 34 is covered on the impact module 32. The impact module inner space 17 accommodating the impact module 30, the impact module 32 and the impact module 35 has at least one side connection part along with the double container inner space part 12, thus forming a plurality of porous parts through which a solution such as sodium acetate, sodium thiosulfate, etc. or an aqueous solution freely flows. A solution such as sodium acetate, sodium thiosulfate, etc. or an aqueous solution can be molten, thus preparing the material of the present invention. Oversaturated sodium acetate aqueous solution is reacted by means of an impact module, but might be reacted by means of friction. In other words, the reaction might occur by means of a friction of a certain element of each impact module of the present invention or by means of a friction between neighboring metallic components. For this reaction, the double container upper layer 10 and the double container lower layer 11 each might have a certain portion causing frictions. Such friction portions are preferably formed in protruded shapes providing more friction surfaces. The double container upper layer 10 is designed to cause friction as a user pushes the same with a certain force, and the friction force as generated causes sodium acetate solution or an aqueous solution to react. The materials that completed reaction are inputted into boiling water in order for sodium acetate solution or an aqueous solution to recover to saturated states. For this operation, a certain necessary device might be equipped at a heating cabinet or a microwave range in order to produce the same condition as the above or to make a condition similar with the above. Sodium thiosulfate solution or an aqueous solution might be used for the above process. The self-heating container of the present invention is most preferably made of stainless steel. The material of the self-hating container might be aluminum or a synthetic resin material having a specific condition appropriate for the manufacture of the container.
